Question

Si a/b = c/d = 3, donde b+1 = d y a + b + c + d =52, halle la suma de la cifras de a
Con solución porfa.

Answer 1

a = 3b

c = 3d = 3(b + 1)

------------------------

3b + b + 3(b + 1) + (b + 1) = 52

4b + 3b + 3 + b + 1 = 52

8b = 48

b = 6

---------------

a = 3b

a = 3(6)

a = 18

-------------------

Suma de cifras:

$\huge{ \boxed{9}}$
